A voltage stabilizing method for power supply driving includes: receiving an input current from a power supply, detecting whether the input current is subject to at least one of interference, undervoltage, overvoltage and short circuit, proceeding to the next step if the input current meets the requirement, otherwise outputting the current through the ground wire and repeating the detection; processing the current by zero-state response and outputting a sinusoidal drive current; detecting the type and working parameters of a connected electrical product, and adjusting a required voltage and a required current frequency according to the detection; and detecting the stability of a loop load, transferring the current to the load if it is detected that the stability of the loop load meets the requirement, and going back to step S1 if it is detected that the stability of the loop load does not meet a preset standard.
